Gun-lock assembly

Abstract

A gun-lock assembly of a toy gun is disclosed to have a gasket ring mounted on the periphery of a piston near its rear end and peripherally stopped at the peripheral wall of an accommodation chamber of the gun-lock housing. When an intake flow of gas is guided into the piston, the gasket ring is moved with the piston relative to the housing to extend an airtight space in the accommodation chamber for receiving the intake flow of gas to enhance the recoil of the toy gun.

1 . A gun-lock assembly, comprising:
 a housing, said housing comprising an accommodation chamber longitudinally extending through front and rear ends thereof, an opening transversely extending across a middle part thereof at a rear side relative to said accommodation chamber for allowing movement of a hammer of a firing control mechanism, and an end block affixed to the rear end thereof;   a piston inserted through the front end of said housing into said accommodation chamber, said piston comprising a stepped axial hole axially extending through front and rear ends thereof and a radial gas inlet located on the periphery thereof in communication with said stepped axial hole;   a first spring member mounted in said stepped axial hole near the front end of said piston;   a stopper bolt supported on said first spring member and movable to close the front end of said piston upon a supply of a forced flow of gas through said radial gas inlet into said stepped axial hole;   a second spring member mounted in said stepped axial hole and connected between an inside wall of said piston and said end block;   wherein a gasket ring is mounted on the periphery of said piston near the rear end of said piston and peripherally stopped at the peripheral wall of said accommodation chamber of said housing, said gasket ring being movable with said piston relative to said housing to extend an airtight space in said accommodation chamber for receiving a supply of a forced flow of gas.   
     
     
         2 . The gun-lock assembly as claimed in  claim 1 , wherein said piston has a rear hole on the rear end thereof; said rear hole being stopped by said end block before the supply of a flow of gas through said radial gas inlet into said stepped axial hole.
